Photorealistic boudoir portrait of a fictional adult woman, 28 years old, glossy black hair in a smooth low ponytail held with a plain knotted cord tie, smooth warm skin, polished makeup with defined brows and a confident direct gaze, wearing slate-blue satin corset lingerie set with ice-white lace trim and a sheer grey robe slipped off one shoulder, standing in a slate-blue room at tall windows opening onto a stone sea terrace, one line of plain solid-colour pennant flags in slate, ice blue and white above the terrace, every flag completely plain with no letters, numbers or emblems anywhere, cool evening light, elegant sensual atmosphere, soft cinematic light, tall portrait composition, high detail
